This report presents results of the first six months of subcontracted research on high-efficiency, single-junction, monolithic thin-film amorphous silicon solar cells. In this work, facilities and laboratory procedures were established that are dedicated to the fabrication and evaluation of amorphous silicon films prepared by flow discharge deposition. Three glow-discharge deposition systems were set up for materials studies and device fabrication. Microcrystalline film depositions onto 7059 glass as well as onto a polyimide substrate have been accomplished. The polyimide substrates have been evaluated with particular attention to analyzing surface defects. It has been learned that the quality of the intrinsic material is extremely sensitive to residual phosphorous contamination within the deposition systems. Parameter testing, which is designed to optimize the systems, is an ongoing effort. Systems for depositing the stainless steel back contact as well as the indium tin oxide (ITO) front contact were also established. The design and construction features of a monolithic, series-connected amorphous silicon solar cell having a large area are also presented.
